hello, other users have reported such issues when programs like speedbit video accelerator or similar software/firewalls that interferes with your network traffic was installed on their pc...

do not have any thing installed like that

soo...no help out there for this???

You can check the network.http.* prefs on the about:config page.

• http://kb.mozillazine.org/about:config

Reset network.http prefs to the default value via the right-click context menu -> Reset if they are user set (bold).

Check at least:

• network.http.accept-encoding (default: gzip,deflate)
• http://kb.mozillazine.org/network.http.accept-encoding

Reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.

• Press and hold Shift and left-click the Reload button.
• Press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
• Press "Command + Shift + R" (MAC)

Did not help. Error does not show up in safe mode.

If it works in Safe mode or with all extensions (Tools > Add-ons > Extensions) disabled then try to find which is causing it by enabling one extension at a time until the problem reappears.

Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

I can get into Yahoo mail when my computer is in safe mode with networking...not when firefox is in safe mode. Still trying to get this to work right. Sometimes your own help pages give the same error.

If it works in Windows Safe mode then you have a problem with other software, likely security software or a system driver, that is running on your computer.

You can use the MSConfig program or the Autoruns utility to see which software and services are getting started.
